Thats fine for use but then you end up a setup like RPMs ... *shudder* ...
where every time you update a RPM you find another dependency ... only to
have it require another thing etc. It is much better to store this sorta
thing in meta info about the package and let the retriever crawl
edependency list *without* downloading jars.
